Green or Blue?

Government have finally produced a 'strategy document' on decarbonizing those UK homes that cannot run on electricity (https://www.theguardian.com/environment/2021/aug/17/uk-homes-low-carbon-hydrogen-economy-jobs). The strategy document reveals an intention to convert 3 million UK households to using 'low carbon' hydrogen fuel in an initial phase. The strategy aims to 'attract' circa £4bn of investment by 2030. This, is seen, as potentially rising to £13bn by 2050. Many high technology jobs would be created in the process. The strategy, however, lacks clarity in a number of places. Firstly, there seems uncertainty whether household bills and/or the Treasury would pay for the conversions. Secondly, it looks as if the intention is to use both 'green' (from water) and 'blue' (from natural gas) hydrogens. 'Green hydrogen' is genuinely low carbon. Burning it only produces water. In contrast, recent studies suggest that 'blue hydrogen', has an impact on global heating, worse than that generated by simply burning natural gas. This is as a consequence of carbon dioxide and methane escaping in the conversion process. 'Blue hydrogen' is, in this respect, far from currently being a 'low carbon' fuel. It would be better to plan for a 'green hydrogen' future?
